The United States, which is hosting Pool C at Marlins Park in Miami, plays its first game on March 10 against Colombia, and will then take on the defending-champion Dominican Republic and Canada.

McGee, who was traded to the Rockies by the Rays last January, began the 2016 season as Colorado's closer, but he was shifted out of the ninth-inning role after some rough outings and a June stint on the disabled list for left knee inflammation.

The 30-year-old finished the year with a 4.73 ERA in 57 appearances, including 15 saves in 19 opportunities. He struck out 38 batters in 45 2/3 innings.
